栅极组件短路是造成离子火箭发动机失效的主要原因。本文分析了栅极组件短路的形成原因,利用电热烧蚀原理,消除栅极组件的短路。通过实验研究,获得了栅极组件短路消除的有效方法。应用实验结果表明,这种方法能够有效消除栅极组件的短路现象。 Short circuit gate component is the main reason for the failure of the ion rocket engine. This paper analyzes the formation of short circuit gate components, the use of electrothermal ablation principle to eliminate the short circuit of the gate assembly. Through experimental research, an effective method to eliminate the short circuit of the gate assembly is obtained. The experimental results show that this method can effectively eliminate the short circuit of the grid components.
